What an import guide must decide before purchase

A useful trade guide on imports is more than a packing list. It is a risk-control plan that connects the purchase order, customs entry, freight movement and payment obligation before the importer commits funds. For a small or mid-sized importer, the key question is not only whether the goods can be bought at a competitive unit price. It is whether the shipment can be legally entered, correctly valued, classified, insured, financed and paid for without avoidable holds or disputes.

The practical starting point is to answer seven questions before issuing a purchase order: who will act as importer of record, what tariff classification applies, whether the product needs a permit or special certification, which Incoterms rule fits the transaction, which payment method matches the risk level, which documents are required for clearance, and whether any party or route creates sanctions or diversion concerns. These questions belong together because a mistake in one area often creates cost in another. A low price can disappear if the importer later discovers additional duties, delayed entry, storage charges, rejected documents or payment exposure that was not priced into the deal.

Build the import file around customs facts

Every import should have a basic transaction file before the goods move. The file does not need to be complex, but it should be complete enough for a customs broker, bank, insurer or internal finance team to understand what is being bought, from whom, under which terms, and for which destination market.

Product identity and tariff classification

Tariff classification is the foundation for duty calculation and many other import controls. In the United States, the Harmonized Tariff Schedule is maintained by the U.S. International Trade Commission, while Customs and Border Protection is responsible for customs administration and rulings. The USITC’s own guidance notes that classification of imported goods is first the importer’s responsibility, while Customs interprets the tariff schedule for particular goods. This distinction matters because a supplier’s HS code on a commercial invoice may be useful background, but it is not a substitute for the importer’s own classification review.

A good product description should include material composition, function, technical specifications, model numbers, intended use, packaging and any accessories shipped with the item. For products such as chemicals, food, medical items, electronics, textiles, batteries or controlled technologies, generic labels such as “parts,” “samples” or “accessories” are not enough. A vague description increases the chance of broker questions, customs holds or later corrections.

Value, origin and permits

Customs value should be supported by commercial records, not estimated from resale price. CBP public guidance for U.S. entries states that the commercial invoice should show the price paid by the buyer for the goods, rather than the amount for which the goods will later be sold in the United States. Other markets apply their own customs valuation rules, but the same control principle applies: the invoice, purchase order, payment record and shipment documents should tell the same commercial story.

Import permits also need early review. USAGov guidance updated on February 24, 2026 states that most goods do not need a license to enter the United States, but some items may require a license, permit or other certification from the relevant agency. The important lesson for importers in any market is to check the product regulator, not only the customs authority. A customs broker may help with entry, but food safety, consumer product safety, agricultural, environmental, health or dual-use controls may sit with other agencies.

Match Incoterms to payment exposure

Incoterms are often treated as freight shorthand, but they are risk allocation rules. The International Chamber of Commerce’s Incoterms 2020 framework contains 11 rules that define responsibilities between seller and buyer for tasks such as delivery, carriage, insurance, documentation and customs formalities. Public guidance from the International Trade Administration emphasizes that Incoterms clarify tasks, costs and risks, but do not cover every condition of a sale.

Why Incoterms are not payment terms

One frequent import mistake is assuming that an Incoterms rule also determines when ownership transfers or when payment is due. ITA guidance makes clear that Incoterms do not specify the method or timing of payment, do not identify the goods or contract price, and do not by themselves settle title transfer or dispute resolution. Those points must be written into the sales contract, purchase order or payment instrument.

For example, an importer buying on FOB terms may take freight risk from the port of loading, while payment may still be due by letter of credit, documentary collection, cash in advance or open account. The delivery rule and the payment rule operate together, but they are not the same rule.

Practical term choices for importers

For importers, the right Incoterms choice depends on control and capability. EXW can appear attractive because the seller’s obligation is limited, but it may create practical problems if the buyer cannot manage local export formalities in the seller’s country. FOB may work for ocean shipments where the buyer wants control after loading, while FCA is often more suitable for containerized goods because delivery can occur at an agreed place before the goods are loaded on a vessel. CIF or CIP may be convenient when the seller arranges carriage and insurance, but the importer should still review the insurance level, claims process and destination charges.

The contract should avoid unclear phrases such as “FOB factory” or outdated local habits that conflict with Incoterms 2020. State the rule, named place or port, version and responsibility for documents. A clear clause such as “FCA Shanghai warehouse, Incoterms 2020” is more useful than a vague shipping instruction.

Choose payment terms by shipment risk

Payment terms should reflect the importer’s trust in the supplier, the availability of independent documents, the resale urgency of the goods and the consequences of non-performance. The International Trade Administration’s trade finance materials describe several core methods used in cross-border trade, including cash in advance, letters of credit, documentary collections, open account and consignment. Each method shifts risk differently between importer and exporter.

Payment method	Main importer benefit	Main importer risk	When it may fit
Cash in advance	May secure production or a price for scarce goods	Importer pays before receiving control of goods or documents	Small trial orders, customized goods, or sellers with strong leverage
Letter of credit	Payment is tied to presentation of required documents	Cost, bank fees and document discrepancies can delay release	New supplier relationships, higher-value shipments or politically sensitive routes
Documentary collection	Banks exchange documents for payment or acceptance without the full cost of an LC	Banks facilitate but generally do not guarantee payment or verify goods	Established relationships in stable markets
Open account	Goods are shipped before payment is due, supporting importer cash flow	Supplier may price in credit risk or limit availability if trust is weak	Long-term supplier relationships with reliable performance records
Consignment	Payment may follow resale of the goods	Complex inventory, title and insurance issues	Distributor arrangements with strong controls and clear inventory reporting

For importers, the safest payment method is not always the cheapest or the most practical. A letter of credit can reduce some seller performance concerns if documents are correctly structured, but it does not prove that goods are commercially perfect unless inspection documents, certificates or independent testing are included and enforceable. Documentary collection can be efficient, but ITA materials warn that banks act as facilitators and do not provide the same payment guarantee as a letter of credit. Open account is helpful for importer cash flow, yet it depends on supplier willingness and a credible credit relationship.

Do counterparty and route screening before money moves

Import risk is not limited to duties and freight. A transaction can create compliance exposure if the supplier, consignee, intermediate party, vessel, bank or end user is restricted. Screening should be completed before deposits are paid and repeated if the shipment structure changes. See also: Customs and Compliance.

For U.S.-connected transactions, the Consolidated Screening List is a practical public tool because it consolidates trade-related restriction lists maintained by the Departments of Commerce, State and Treasury. Its guidance explains that the list includes sources such as the Denied Persons List, Unverified List, Entity List and other U.S. government lists. The CSL also provides fuzzy-name search functions, which is useful when company names are translated from non-Latin alphabets or appear with spelling variations.

Screening should not be a one-click ritual. Importers should compare legal names, addresses, beneficial owners where available, bank details and known affiliates. If a supplier changes its receiving bank after the pro forma invoice is issued, asks for payment to an unrelated third party, reroutes goods through an unusual country, or refuses to provide manufacturer details, the transaction should be escalated. These are not automatic proof of wrongdoing, but they are warning signs that deserve documentation and approval before funds move.

Protect cash flow with landed cost and document controls

A landed cost estimate should be prepared before the purchase order is final. At minimum, it should include product price, tooling or sample charges, inland origin charges, export documentation charges, international freight, insurance, destination port or terminal fees, customs duties, additional tariffs if applicable, broker fees, inspection costs, domestic delivery and financing cost. If the goods may be subject to antidumping or countervailing duties, the importer should not rely only on the ordinary tariff rate. USITC guidance explains that AD/CVD duties are not ordinary customs tariffs in the Harmonized Tariff Schedule, and the Department of Commerce’s International Trade Administration sets rates in AD/CVD orders.

Documents should be controlled with the same discipline as money. A typical import file may include the purchase order, pro forma invoice, commercial invoice, packing list, bill of lading or airway bill, certificate of origin, insurance certificate, inspection certificate, permits, test reports, payment evidence and broker instructions. The exact list depends on the product and market, but consistency is essential. Product description, quantity, value, currency, buyer, seller, origin and shipment marks should align across documents.

U.S.-bound importers should also avoid relying on old assumptions about low-value shipments. CBP guidance issued in 2025 stated that, beginning August 29, 2025, requests for de minimis entry and clearance for shipments made ineligible under the relevant executive order would be rejected, and filers would need to submit an appropriate formal or informal entry type in ACE with applicable duties, taxes and fees. The broader lesson is that low-value import procedures can change quickly, so recurring parcel importers should check current instructions before building pricing or delivery promises around simplified entry.

Import timeline and control checklist

The best time to manage import risk is before production begins. Once goods are packed and shipped, the importer has fewer options and weaker leverage. A simple timeline helps keep the process under control.

1. Before supplier approval: verify the supplier’s legal name, address, bank details, product capability, certifications and screening results.
2. Before purchase order: confirm product specification, tariff classification, origin, permits, Incoterms rule, payment method, inspection plan and dispute terms.
3. Before deposit or LC issuance: align the pro forma invoice with the purchase order and require any critical documents as payment conditions.
4. Before shipment: review packing details, commercial invoice, bill of lading instructions, insurance, marks and any required certificates.
5. Before arrival: send documents to the customs broker early and resolve classification, value or permit questions before the goods reach the port.
6. After entry: reconcile duties, fees, landed cost, payment balance, received quantity and quality claims while records are still fresh.

For U.S. entries, USAGov guidance states that entry forms must be filed within 15 calendar days of a shipment’s arrival at a U.S. port of entry and must include an importer number. Other jurisdictions have their own timing rules, but the management principle is universal: customs deadlines should be built into the purchasing calendar, not discovered after arrival.

Frequently asked questions

What is the first step in planning an import shipment?

The first step is to define the product accurately and confirm whether it can be legally imported into the destination market. That means reviewing classification, origin, permits, technical standards and restricted-party concerns before negotiating the final price.

Should an importer accept the supplier’s HS code?

The supplier’s code can be a useful starting point, especially if the supplier exports the same product regularly. However, the importer should independently verify the destination-market classification because duty rates, import controls and reporting rules depend on the importing country’s tariff schedule.

Do Incoterms decide when payment is due?

No. Incoterms allocate delivery obligations, costs and risk between buyer and seller, but they do not set the payment method or payment date. Payment timing should be stated separately in the contract, invoice, letter of credit or collection instruction.

Is a letter of credit always safer for importers?

A letter of credit can reduce some payment and document risks, but it is not a full quality guarantee. It works best when the required documents are precise, realistic and connected to the importer’s actual control needs, such as inspection certificates or shipping deadlines.

Why does landed cost matter more than unit price?

Unit price excludes many import expenses, including freight, insurance, duties, additional tariffs, broker charges, storage, financing and inspection. Landed cost gives the importer a more accurate view of margin and helps prevent a shipment from becoming unprofitable after arrival.
